IMPROVEMENT IN MACHINES FOR SAWING WAGON FELLOES.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, NOBLE W. GRAVES, of Winnebago, in the county ofWinnebago, in the State of Illinois, have invented anew and usefulImprovement in Machines for Cutting Wagon Felloes; and I do herebydeclare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to theannexed drawings, making a part of this specification, in whieh Figure Iis a front elevation, with some parts of the frame and table removed.

Figure 2 is a top view.

Figure 3 is a longitudinal sectional elevation through the centre.

The same letters in the several drawiligs refer to the s'ame parts. ,x

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A represents a wheel, constructed with hub, arr'ns, and rim. There areflanges, c c, upon both the outer and inner edges of the rim upon theunder side. The diameters of this wheel and of the wheel for which thefclloes are to be cut is the same. To the outer 'side of these flangessaws or othercutting devices are fastened, so that the distance betweenthe outer and inner saw shall be the same as the depth of the felice tobe cut. Wheel A is made fast, or hung on the lower end of upright shaftD, having its bearings above in boxes B B. C C are pulleys upon shaft D,one loose, the other fast. Motion is given to wheel A bymeans of a beltpassing around these pulleys. v Portions of wheel A and of the saws arecut away, showing niore fully the construction of the wheel and the sawsattached, a a representing the outside and b the inside saw, and c c theflanges. Other cutting tools may be attached to these flanges, and usedin place of saws. E E is the saw table, with its several parts attached.This table is immediately in front of and below wheel A, and its top isparallel to it. This table rests upon the main frame of the machine, andis moved up and down perpendieularly upon the fire bearings or slides 7L7L 7i, the., by means of foot-lever Q. The part of the edge of the tablenext to the saws, and where the felloe is eut out, is constructed ou acurve or circle corresponding with that of the outer saw. This forni ofthe table allows the felloe, when eut and released frein the dogs, tofall at once out of the way. el and c2 are saw-toothed dogs, el beingbolted fast to the table and e2 'made fast to stirrup f, which havetheir bearings in stanchion g. These dogs are slotted, as seen at y, sothat when the table is raised by means of lever Q, the outer saw can doits work without coming in contact with the dogs, and at the same timeenable the dogs to hold both the main bolt and the felloe while beingcut, and until it is released by the movement of lever when it drops outof the way. Itwill be observed that all of the working parts of thismachine are attached to the saw table, and move with it, exceptsaw-wheel A and its attachments and foot-lever Q. The arrangement ofthese several parts I will new explain. Stanehion g is made fast totheunder side of the table. Dog e2, while it is made fast to stirrup f, isalso connected to lever by pitman j. Under the dogs are the shafts 7c,on the ends of which are the stops or gauge-pieces o o. Stirrupf isconnected to crank fn, by Pitman m, and cranks n and p are connected bypitman z. Now, by taking hold of lever z' with the right hand, andbringing it inwards or towards you, dog c2 will be moved in thedirection of dog e1. At the same time, by means of the connectionsalready explained, stops or gauges o o will be moved to the positions ofthe dotted lines 0 o, so that when the table rises they will come upbetween the saws and` out of their way. Bearings, L h h, Ste, may befitted to boxes set in the saw table. :v z are ways upon the top of thetable for the ends ot' tho bolts or planks to rest upon.

To operate this machine, let there be bolts or planks provided of theproper length and thickness.rv Place a bolt or plank with its ends uponthe ways a: x, and withthe left hand push it forward against the stopsor gauges o o. Bring lever t' toward you with the right hand, clampingthe bolt fast between the dogs, and hold it firmly. Place your footupo'n lever Q, and press it down gradually. This will force the tableup, bring the bolt in contact with the saws upon wheel A, put in motionas before described. A felloe will be immediately cut ont. `Then removethe pressure from lever Q, and letthe table descend. vNew throw backlever z', releasing the dogs from their hold. The felloe cut drops, andthe stops or gauges return to their places. Push forward the boltagainst the stops; bring up lever t', as before, clamping the bolt;press down footlever Q, ttc., repeating the operation .each time afelloe is cut. I Z, Ste., are braces, which serve in connection withbearings z. L, die., to steady table E and keep it in a horizontalposition; t is the bearing for lever Q, and s is a stop, which preventslever Q from raising the table too high. F F, 85e., is the mainframework which supports the machine.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. So arranging the adjustable saw table E, and slotted dogs e1 and e2,in relation to the concentric saws a and l, that the piece to be outshall project beyond the table, and be supported by the dogs alone,after being separated, and fall when the dogs are-retracted,substantially as set forth` 2'. The arrangement of the adjustable tableE, vertical guides 7L, supporting rods ZZ, and plate thereto attached,sliding 'upon the depending guide h and lever Q, substantially as setforth.
